Saw a guy napping in a Dyna-Cor(Tech?) van, tinted windows outside our local Post Office at Fields Landing(California). I took a picture just in case, no one around. Maybe just napping but why outside a closed post office?
A friend of mine worked for USPS in the DC area. He would drive to work around 3 or 4AM to avoid the traffic and sleep in his truck until starting time.
They are using independent drivers
